that material from northern Oregon is unlikely to match material from Encinitas. You have a lot of eucalyptus there. In Portland eucalyptus is a hardy plant for the first year, usually not hardy outside for the second year. Probably has something to do with our balmy spring and later winter… not over 3 inches of rain per day, usually.

“rooting base or stalk” as Arora, calls it. Or as I call it a stipe. The rhizimes are especially helpful to me, as is the yellow base of the undegraded sporocarp. I think this is the original Pisolithus tinctorius (=P. arrhizaus) but have no DNA evidence to support that believe.

You didn’t note any ill-effects after sampling it. Either you didn’t consume much (a “taste”?) or the immeature material is edible to some degree. (As are all mushrooms and fungi at least once.)

I believe your observations are important, and will offer a pathway towards Pisolithus in America. Please keep these observations coming!
